No. Regardless of vaccination status you are no longer required to quarantine when you come in contact with someone with COVID-19.
But to be safe, it’s recommended to:
- Wear a mask around others for 10 days
- Get tested 5 days after you’re exposed to COVID
- Maintain physical distancing (even at home) until your test comes back negative
- Watch for symptoms for the next 14 days
- If you do develop symptoms, then self-isolate immediately and get tested.
